What does the envelope alarm zone ALC03 mean on a Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner displays an envelope alarm zone (ALC03), it indicates that the operating conditions are outside of the compressor specifications. Check the operating conditions as per compressor specifications.
Why is my Rittal Air Conditioner showing a high pressure alarm ALB01?
If you are encountering a high-pressure alarm (ALB01) on your Rittal Air Conditioner, it could be due to a high ambient temperature, incorrect coolant filling, or a defective fan. To resolve this, check the device limits, verify the coolant volume, and ensure the fan is functioning correctly.
What causes a high evaporation temperature alarm (ALD07) on a Rittal Air Conditioner?
If your Rittal Air Conditioner is showing a high evaporation temperature alarm (ALD07), it could be due to a high inlet temperature or an incorrect PID valve parameter. Check the valve PID parameters and the alarm delay. If the condenser ambient temperature is at most 35°C, raise the MOP limit (max. 25°C).
What to do if Rittal Air Conditioner displays low pressure differential alarm ALC06?
If your Rittal Air Conditioner displays a low-pressure differential alarm (ALC06), indicating insufficient lubrication, it could be due to operating conditions outside of compressor specifications or device limits, a blocked compressor, or incorrect wiring. Check the operating conditions as per compressor specifications, verify the device limits, and check the wiring.
What does low superheat (LowSH) alarm ALD04 mean on Rittal LCP Rack DX 12 Air Conditioner?
If you're getting a low superheat (LowSH) alarm (ALD04) on your Rittal Air Conditioner, it might be due to incorrect coolant filling, insufficient heat load, or insufficient fan speed. You should check the device limits, verify the coolant volume, and check the fan speed.
Why is my Rittal LCP Rack DX 12 Air Conditioner showing a low evaporation temperature alarm ALD06?
If your Rittal Air Conditioner is showing a low evaporation temperature alarm (ALD06), it may be caused by incorrect coolant filling, insufficient coolant volume, blocked coolant lines, or a closed thermostatic valve. To resolve this, check the coolant volume, check the lines for leaks, and check the thermostatic valve.
What causes the low pressure alarm ALB03 on Rittal LCP Rack DX 12 compressor?
A low-pressure alarm (ALB03) on your Rittal Air Conditioner could be due to incorrect coolant filling, an insufficient quantity of coolant, blocked coolant lines, or a closed thermostatic valve. Check the coolant volume, inspect the lines for leaks, and check the thermostatic valve.
How to fix compressor start failure ALC04 on Rittal Air Conditioner?
If your Rittal Air Conditioner is experiencing a compressor start failure (ALC04), it could be due to an inadequate pressure difference during device startup, excess current or a missing phase on the inverter, or a blocked inverter. Check the operating conditions as per compressor specifications, verify the device limits, and check error codes in the inverter manual.
Why is my Rittal Air Conditioner displaying a high condensing temperature alarm ALD08?
If your Rittal Air Conditioner displays a high condensing temperature alarm (ALD08), it could be due to a high ambient temperature, incorrect coolant filling, or a defective fan on the condenser. Check the device limits, verify the coolant volume, and inspect the condenser fan.
What causes the high pressure compressor 1 alarm ALB02 on a Rittal Air Conditioner?
If your Rittal Air Conditioner is showing a high-pressure alarm (ALB02) for compressor 1, it may be caused by a high ambient temperature, incorrect coolant filling, or a defective fan. Check the device limits, verify the coolant volume, and ensure the fan is functioning correctly.
